Here is Calacatta Laza (disregard the ledge stone. That’s similar color to our fireplace downstair)

And here is Calacatta gold.

I think you should add some crown molding to the top of the cabinets and a baseboard molding at the bottom to give them a more "finished" look. Also wondering what you do for venting the stove that is in the island?

Thanks Damiarain. That’s a great point about the fabricators. The quartzes are sold by two different companies so I should do some research into their reviews. Is there another countertop you think would look good?

I would visit the slabs in person. Those pieces are not enough to come to a final decision. The movement and pattern will help guide you in which direction you will go.

The fabricator should also create a template and view as to how these slabs will be cut and how the pattern will flow within the area covered.

Please make sure they do this before you go ahead with the installation.

Out of the two I prefer the Calacatta Gold slightly more. Not sure why, maybe because it's a bit warmer.

I would also consider Astoria granite. It's not as white as the two quartz patterns you're looking at but it doesn't have an much veining which means you should have an easier time with seams.

Here's a picture of a kitchen with similar color cabinets to your with Astoria granite. Ignore the backsplash.

You have too many corners for a heavily veined quartz to come out well. Your seams will not be like in natural stone. They will be quite visible and likely not have the veining match. Buying an extra $3500 slab can help, but there is no guarantee.

With the number of seams you may have, you might want to use a countertop with more or less of a pattern. I can barely see my seam because of the pattern yet the pattern is not so busy that it fights with the wood - but if the pattern is busy - don't take it up the wall because along with the wood grain, it will overwhelm the kitchen:

You could do something with a very light pattern like LG Soprano.

In my opinion, backsplash in kitchens with wood cabinets look best if they are very simple. Here is my wood kitchens idea book - many of these have cream or white subway tile or a similar simple splash. The style of quartz or granite used as a splash is somewhat modern, and might not play well with the older cabinets.

The kitchen is great. Very rustic. Not marble-is hat all, to me. I don’t see either of those marble wannabes living well there. I think more soapstone-looking.

Marble=Italy. North American mountains - slate, soapstone, maybe honed granite.

Actually, some marble is from the US - Danby marble from Vermont is just one:)

jhmarie - jpp's comment is about style, not origin of stone.

marble says: elegant

soapstone, or honed granite say: rustic

Yes - I understand your point but the OP said they would like to lighten the space. One can find wood kitchen's with marble counters and washstands with marble tops in a rustic setting - but it will look rather vintage too. This would not be the large vein type marble seen in some "marble look" quartz but more of this look - not a bold pattern:

The OP may not want rustic even though they live in the mountains - in which case they just might want a simple white quartz or quartz with less pattern so as to match the seems better - especially if wanting it for the backsplash too. If quartz seems to not be natural enough, then they can look at a lighter granite (but OP can't find one she likes) and pair it with a tile backsplash, or do a short 4" splash and just paint the backsplash area a light color.

Colorado and Montana quarry marble too. It is rather elegant looking and somewhat bold in pattern:

Th OP's cabinets are very interesting - at first I thought they were older - like MCM, but I've seen modern cabinets with the same look - so they have a lot of leeway as to what style they want.

Thank you so much for your feedback! I should have included images of the rooms that feed into the kitchen. Our kitchen is open to our small family room(we have young children so excuse the mess!) and flows down into our living room. I don’t really want the kitchen to feel too kitcheny since it’s integrated with our hanging out area. You can see that the rest of our house isn’t particularly rustic.

I would like our countertop to feel clean and more modern rather than traditional. I’m bummed to hear the Calacatta may not work because of seams, but also really happy to hear it before we spend all that money! Any other countertop suggestions are greatly appreciated. Thank you Houzz community!!
